Abstract
Tetraphenylmethane (1 ) and several functionalized
tetraphenylmethanes 4 -7 , all of them useful building blocks for
the construction of tetraarylmethane frameworks, are readily synthesized
by improved standard procedures in multigram quantities. The structure
of compound 5 has been additionally corroborated
by an X-ray structure analysis. The novel class of tetrakis(thiazolylphenyl)methanes 8 showing a significant blue emission upon
UV-excitation can be prepared in good yield by Hantzsch synthesis
starting from the tetra(α-bromoketone) derivative 4b .
Key words
acylations - alkylations - cyclizations - dendrimers - heterocycles
